Latency has more impact on Skype call quality than bandwidth. Lirneasia's research brings out that SLT's ADSL's is not bad in this regard in Feb '08, on par with BSNL from Chennai. By Oct '08 however, latency has got worse, for both SLT and Dialog connections tested. This may indicate that Skype is now able to deal better with high latency connections. There has not been a single release of Skype that has not touted improvements to voice (and video) quality. Clearly, underlying A/V codecs are improving too, evident in products such as iChat on OS X as well. I have used Skype on a Samsung i780 running Windows Mobile 6.1 and the beta version of Skype for Windows Mobile. Skype call quality over wifi as well as 3G on Dialog from Colombo is indistinguishable from Skype running on a PC connected to the 'net via Dialog's Wimax. Good news for us. Bad news for mercenary telcos. Sanjana Ranmalee,
